Application filed July 5, 1906. Serial No. 324,910.

To LZZ wwnz it may con/067%:

Be it known that I, TH'oMAsHENDEEsoN, a citizenaof theUnited States,residing at Tennessee Colony, in the county of Anderson and State ofTexas, have invented a new and useful Harrow, ,of which the following isa specification.

This invention has relation to harrows g and it consists in the novelconstruction/and arrangement of its parts, as hereinafter shown anddescribed.

The object of the invention is to provide a harrow, preferably of thespring-tooth type, the teeth of which are mounted upon bars which areadapted to swing in horizontal parallel relation. Sleeves are mountedupon the said bars and are pivotally attached at their ends to the same,and as the said bars swing, as above indicated, the said sleeves arecarried in a forward or rearward direction; but the said sleeves at alltimes maintain parallel relation with each other.

A means is provided for securing the arms at the proper angle orvinclination with relation to the beam of the harrow, and a means isprovided for adjusting the lateral position ofthe handles with relationto the beam of the harrow. Also braces are provided for reinforcing thearms in relation to the beam of the harrow.

In the accompanying drawings, forming a part of this specication, Figure1 is a top plan view of the harrow. Fig. 2 is a side elevation of thesame, and Fig.` 3 is a longitudinal sectional view of part of the beamof the harrow.

The harrow consists of the beam 1, upon the under side .of which issecured a plate 2. The longitudinal edges of the said plate 2 arelocated beyond the vertical sides of the beam 1, and the said plate 2 insuch' ortions as are beyond the vertical sides of t e beam 1 is providedwith the perforations 3. The

ltransversely-extending bars 4,4 are attached to the under side of thebeam 1 and are preferably countersunk in the same. The arms 5 5 arepivotally attached at their inner ends to the endsof the bars 4. Thesleeves 6 6 are pivotally attached at their ends to the bars 5 5. All ofthe said sleeves 6 are of the same construction, and a description ofone will answer for all.

Each sleeve consists of the intermediate portion 7, which is adapted toreceive the said sleeve, and the set-screw 10 is screwthreaded into thesaid boss 9. The inner end of the set-screw; 10 is adapted to engage thetooth 8 and maintain the same in proper relation with the said sleeve.

The sleeve is provided at its ends with the horizontal 'eX- tensions11.11, which are secured, by means of the pivot-bolts 12, to the arms 55. The rods 13 are'pivoted at their rear ends to the forward arms 5 andare provided at their forward ends with the hook portions 14, which areadapted to enter the perforations 3 of the plate 2. The said hooks 14may be lretained within the perforations 3 by they beam 1 and may swinghorizontally thereon.

The plate 19 is pivoted at the rear end of the beam and may swinghorizontally thereon.

The said plate 19 is provided with a number of perforations 20, any oneof which is4 adapted to receive the bolt 21 whereby the yoke 22 is fixed.to the said plate. The upper ends of the yoke 22 are provided with anumber of perforations 23, which are adapted to receive the bolts 24,whereby the upper ends of the yoke are secured to the handles 17.

From the above description it is obvious that the angle of inclinationof the said handles 17 with relation to the beam 1 may be varied to suitoccasion and fancy and that the said handles may be swung laterally andsuitably secured.l It is also obvious that the arms 5 may be swung inparallel relation, so as to bring the working ends of the teeth 8 insubstantial alinement across the harrow, or the teeth of one side of theharrow may be arranged in a row which extend at an angle to the line ofteeth located on the other side y of the harrow.

There is a sleeve located under the beam 1 at a oint between the innerends of the arms 5. rlzhe said sleeve 6 is fixed with relation to thebeam 1 and carries the harrow-tooth 8, as above described.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. A harrow comprising a beam, arms pivoted to the beam in parallelrelation to each IOO IIO

other, sleeves connecting said arms together, and harroW-teeth carriedby said sleeves.

2. A barrow comprising a beam, arms pivotally attached to said beam andadapted to swing laterally With relation thereto, harroW- teeth carriedby said arms, and handles pivoted to the beam and adapted to be adjustedlaterally thereto.

. 3. A harroW comprising a beam, arms pivoted to the beam, harroW-teethattached to said arms, handles pivoted to the beam and means foradjusting the vertical position of the rear ends of the handles and thelateral position thereof.

4. ,A harroW comprising a beam, arms pivotally attached in parallelrelation to the beam, sleeves pivoted at their endsto said arms, andharroW-teeth retained Within said sleeves.

5. A harrow comprising a beam, arms pivoted to said beam in parallelrelation to each other, sleeves pivotally attached at their ends to saidarms, barrow-teeth retained by said sleeves and adapted to be adjusted1ongitudinally therein, and set-screws passing through the sleeves andengaging said harro'W-teeth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.

THOMAS HENDERSON.
